The finished roughcast should be checked as the following before being accepted:
1)the roughcasts must be forged by hydraulic press with the total forging ratio no smaller than 4;
2)the Austenite grain size must be equal or over 5, according to GB/T6394;
3)there must be at least one forging with an extra length of 250mm from the same furnace No. for the purpose of the demander's retest;
4)after the process of annealing or normalizing and high-temperature tempering, the forging’s hardness HB must be no more than 240;
5)such defects as crack, mezzanine, fold and forging injury are not allowed on the surface of the forging after rough process;
6)from the surface to as deep as 80mm, no defects with a diameter longer than 2mm are allowed, nor the suggestion of length extension;
7)apart from the range mentioned in 6), extensive and continuous defects are not allowed in the center part of the forging.

Introduction
Silicon nitride (Si3N4)-based ceramics have a large number of industrial applications because of their
excellent mechanical and thermal properties.
The protective layer was assumed to retard any further oxidation of the grain boundary phases at 900 °C and 1000 °C.

A commercial bentonite from Riedel-deHäen ( CAS number 1302-78-9) with cation exchange capacity (CEC) 54 meq/100g was used as starting material.
The [Ca(2,2¢-bipyridine)3]-bentonite/graphite composite was then taken off from the mold and dried at 70°C in an oven for 6 hr., before polishing with fine grain sand paper.

During the experiment process, a large number of specimens were studied and a certain range of the laser cladding technology parameters were preliminary confirmed when the laser spot characters and powder feeding rate were kept constant.
The crystalline grain size is keeping growing and dendrite crystal would change to cellular crystal.

Maximum aggregate grain size size of 8 mm was used with a 20 mm protective layer of concrete for the main flexural reinforcement bars.
Displacement and number of rows were chosen according to the EC2 so that shear failure would occur in the area with shear reinforcement.

Introduction
Water hyacinth is a type of plant that floats on the water, is green in color, has a single oval-shaped leaf, and slippery has a flower in the form of grains and petals.
However, there was no strong binding due to the absence of functional groups C=O and C=N at wave number 1690–1640 cm–1, which was a sign of the occurrence of bonds between chitosan-EDTA and chitosan-cellulose [16].
